INTERLOCKING MIETAL SHEET-PILIN G.

To all whom it may concern:

Be it known that I, GEORGE II. BARBOUR, of Pittsburg, Allegheny county,and State of Pennsylvania, have invented a new and useful Improvement inInterlocking Metal Sheet-Piling, of which the following is a full,clear, and exact description, reference being had to the aceom anyingdrawings, forming part of this specification, in which Figure 1 is aplan view of two parallel rows of sheet piling braced and interlocked toeach other, which are made u of two of the special shapes of my improvepiling; Fig. 2 is a similar view composed of one form of my piling; Fig.3 is also a similar view which is composed of one of the shapes shown inFig. 1 and another form of piling which is interlocked therewith; Figs.4, 5 and 6 are detail end views of the three shapes of sheet pilingshown in Figs. 1, 2 and 3.

The invention relates to metal sheet iling employed in constructingretaining wa ls for excavations, foundation Walls, piers and in formingcaissons, bulk heads, docks, wharves and similar structures used insub-marine work, and it articularly relates to metal sheet piling havinintegral interlocking members and which are interlocked with similarmembers on a line therewith, or which can be interlocked with sheetpiling members extending at an angle thereto.

The precise nature of my invention will be best understood by referenceto the accompan ing drawings which will now be descri ed, it beingpremised, however, that various changes can be made by those skilled inthe art, without departing from my invention as ointed out in theappended claims.

The tiiree shapes used in the construction shown in Figs. 1, 2 and 3will be best understood by reference tojFigs. 4, 5 and 6.

In Fig. 4, the letter A represents the rolled shape of one form of mysheet piling; in which, the numeral 2 designates the web which isprovided at each end with the double headed engaging member 3, havingthe heads 6 is a hook guard adjacent to the head A; which hook guard inconjunction with the head 4 forms a channel to receive a head of thenext section similar to the head 3. Each end of the web 2 of thissection is also provided with a hook guard 8 and a rojecting guard 9which form a channe 10 similar to the channel 7, and for the samepurpose.

Specification of Letters Patent.

Application filed January 16, 1909.

Patented June 29, 1909.

Serial No. 472,436.

In Fig. 5, I have shown a rolled section B having the web 2 which isprovided at each end with the double headed engaging ortion 3 and thehook guard 6, similar to t rose res ective members in the section A.

n Fig. 6, I have shown a section C, having the web 2, each end of whichis provided With the double headed engaging portion 3.

The construction or assembling of the piling as shown in Fi 1 iscomposed of sections A and B, which ilIustrates two )arallel rows ofsheet piling, each row of pi ing is composed of sections A and B, eachmember of each row is interlocked with each other by means of a sectionB and the two rows of parallel iling are interlocked with each otherthereby. The double headed engaging member. 3 of the section A lieswithin the channel 7 of the member B and engages the head 4 or hookguard 6 thereof, while the double headed portion of the member B liesWithin the channel 7 of the section A and engages the head 4 or hookguard member 6 thereof and both sections are held from longitudinal andhorizontal displacement thereby. These two parallel rows of sheet pilingare interlocked with each other by means of the double headed portion 3of the transverse section B engaging the hook guard member 8 orprojecting member 9 of the sections A.

The construction shown in Fig. 2 is composed entirely of the sections Awhich also illustrates two parallel rows of sheet iling, each member ofeach row being interloc ed by means of the double headed portion 3 inconjunction with the hook guard member 6. The two parallel rows of sheetpiling are interlocked with each other by means of sections A, thedouble headed member thereof engaging the hook or projecting guardmembers S or 9 of the sections composing the parallel rows.

In Fig. 3 I have illustrated two parallel rows of sheet iling which arecomposed of the members and C. These para lel rows are interlocked bymeans of the transverse section C. The double headed end of the sections0 in the parallel rows lie in the channels 7 of the sections A andengage the head 4 or hook guard 6 thereof. The double headed ends of thetransverse sections C lie within the channels 10 of the members A andengage the hook or pri'rjecting guard members 8 or 9 thereof.

It will be readily understood by reference to Fig. 2 that the twoparallel rows of sheet piling ma be interlocked to each other by meansof the sections C or B, and it will also be understood that a series ofthese parallel rows, if composed of the sections A can be lockedtogether by either of the three sections A, B or C.

The advantages of my invention result from the use of a sheet metalpiling section the ends of which com )rise a double headed engagingmember which lies in a channel provided with two members which areengaged By the double head of the adjacent sect-ion.

so in providing a sheet piling section having a double headed engagingmember, a hook guard adjacent thereto, and a second hook guard member,having a projecting guard member adjacent thereto. The double headedengaging member in conjunction with its hook guard form one receivingchannel for an adjacent section while the second hook guard inconjunction with its rojecting guard forms a second receiving CHLHHGIIOIanother adjacent section.

By this construction of iling, I am enabled to form a series of para lelrows of sheet piling, each member of which is interlocked with itsadjacent member in the same row. Also in which each member of eachparallel row is interlocked with a similar member in a row paralleltherewith. I am also enabled to place adjacent sections at variousangles to each other by reason of the double headed engagin portion,which allows a partial rotation of tIe members in either direction froma straight line.

I claim:

1. In sheet metal piling, a piling section having a web with an integraldouble headed engaging portion at the longitudinal edge thereof, and asecond piling section having engaging members adapted to engage one ofthe heads of the double headed member of the first section,substantially as described.

2.
